��cr� Tyco Suppression Systems . ANSULINCORPORATED � S�� MARINETTE,W554E 3-2542 IS09001REGISTERED �"^^^'V.ansul.com GENERAL BULLETIN NO. 4260 Date: May 23, 2000 To: All Authorized Restaurant System Distributors and OEM's From: Dave Pelton — Market Development Manager Subject: PIRANHAO Fire Suppression Systems Fire Sprinkler Connection Since the commercial introduction of PIRANHA Water-Assisted Suppression Systems back in January `98 we have been working hard to provide you with the best and most advanced restaurant fire suppression system i� t�s indus#r,�. To that end we are pleased to announce that connection to an alternative water supply source such as a fire sprinkler system is permitted. Noted below is an overview of the requirements. Before considering any PIRANHA dedicated waterline connection, make certain the connection and the water source to be used, is adequate for the number and size of PIRANHA system tank(s) needed. The water source connection and the dedicated waterline for the PIRANHA system, must be designed and installed in accordance with the appropriate NFPA standard(s) (i.e., NFPA 13—sprinkler waterline connection; NFPA 17A & NFPA 96 — domestic waterfine connection), the UL 300, PIRANHA Design, fnstallation, and Maintenance Manual (P/N 423385), and the authority having jurisdiction. NOTE:The piping requirements in NFPA 13 need ONLY be followed, when the PIRANHA dedicated waterline is connected to a wet pipe sprinkler system, and apply only to the waterline portion of the PIRANHA system. The requirements in NFPA 13 DO NOT apply to the PIRANHA system or the waterline connection when the dedicated waterline is connected to the domestic water supply. The PIRANHA system has been tested, evaluated, and listed to be used WITHOUT any additional back-flow prevention needed. However, if the PIRANHA system is to be connected to an existing sprinkler system, or is to be included as an addition to a sprinkler system currently being designed or under construction, make certain all back-flow prevention, existing or intended, is reviewed and approved prior to PIRANHA system installation by the appropriate authority having jurisdiction. • "ONLY" connections to wet pipe sprinkler systems are acceptable. Gry pipe and pre-action type sprinkler systems are NOT PERMITTED for use with PIRANHA. • The dedicated PIRANHA system waterline tap to the sprinkler system must be made by an appropriately licensed sprinkler fitter/contractor_ All pipe, fittings, and hangers from the sprinkier tap/connection to the PIRANHA system water valve in the ANSUL AUTOMANo Regulated Release Assembly and/or Regulated Actuator Assembly(s) must be made in accordance with the "applicable" requirements of NFPA 13. Use of plastic pipe and fittings for this connection is not acceptable. • For fire sprinkler system connection the minimum PIRANHA dedicated waterline pipe or tube size must be 1". Multiple PIRANHAtank systems may require larger size pipe as required.
